Following a month of discussions involving technical leaders, drivers, team principals, the sport’s executives, and the FIA, Formula 1 has introduced a series of modifications to its contentious 2026 regulations to address some challenges encountered during the first three races.
The primary objectives have centered on four areas: 1) enhancing the excitement of qualifying, 2) minimizing the risk of dangerous closing speeds between cars that could lead to serious accidents during races, 3) lowering the chances of collisions at the start line, and 4) anticipating potential issues teams may encounter in wet conditions.
These modifications still require approval from the FIA’s World Motor Sport Council but are expected to be implemented when F1 resumes at the Miami Grand Prix on May 3.
Despite a comprehensive list of adjustments resulting from the final meeting between team leaders, the FIA, and F1 on Monday, the sport has emphasized that these changes are merely minor adjustments across several areas rather than a complete overhaul of the regulations.
The complexity of the latest generation of cars means that the changes are inherently filled with F1 terminology β key terms are clarified below.
MGU-K: This refers to the “motor-generator unit – kinetic,” which serves dual functions. Firstly, it transfers electric power from the battery to the rear wheels, and secondly, it operates in reverse to generate electricity from the rear wheels to recharge the battery while decelerating the car.
Kilowatts (kW): A unit of electric power that is likely familiar from household appliances. The maximum power that the MGU-K can both generate and recover is limited to 350kW.
Megajoules (MJ): Another familiar unit used to quantify the amount of stored electrical energy. The battery in an F1 car’s hybrid system is allowed to store a maximum of 4MJ of usable energy at any given time.
Superclipping: A method of recharging the battery in an F1 car by utilizing the MGU-K to redirect power produced by the V6-turbo engine to the battery while the driver is fully accelerating, typically at the end of straights or during high-speed corners. Under the original regulations, this was restricted to 250kW instead of the maximum potential of 350kW for the MGU-K. This involuntary deceleration has faced criticism from drivers.
Lift and coasting: This technique allows for the recovery of the full 350kW via the MGU-K by easing off the throttle early and allowing the car to coast before applying the brakes for the next corner.
What’s changed?
Qualifying
The FIA’s explanation: “Modifications to energy management parameters, including a reduction in the maximum allowed recharge from 8MJ to 7MJ, aimed at curbing excessive harvesting and promoting more consistent flat-out driving. This adjustment targets a maximum superclip duration reduced to approximately 2-4 seconds per lap.”
What it means: Capping the energy that can be harvested per qualifying lap to 7MJ will slightly lessen the “unnatural” driving behaviors that have been central to driver complaints this season. The usable capacity of an F1 car’s battery is 4MJ, so instead of trying to charge the battery twice per qualifying lap to achieve maximum power on the straights, the driver will now aim for one and three-quarters times. The extent of the impact remains to be seen, but if only 2-4 seconds of superclipping is necessary per lap β as indicated by the FIA β that will decrease the number of high-speed corners and straights where the car slows down despite the driver applying full throttle. However, limiting the amount of recoverable power will also reduce the deployable power, resulting in slower overall lap times.
The FIA’s explanation: “Peak superclip power has been increased to 350 kW, up from the previous 250kW, further decreasing the time spent recharging and reducing driver workload on energy management. This will also apply in race conditions.”
What it means: Think of this as akin to a fast-charging cable for your phone. By boosting the rate of energy that can be recovered through superclipping by 100kW, the battery will charge more quickly, thereby limiting the duration of superclipping. It should also remove the necessity to lift and coast during qualifying laps, as that had previously been the sole method to achieve the full 350kW recharge rate since superclipping was restricted to 250kW. However, increasing the superclip power will lead to more deceleration during the process, which may still appear unusual from onboard footage.
The FIA’s explanation: “The number of events where alternative lower energy limits may apply has been raised from 8 to 12 races, allowing for greater adaptation to circuit characteristics.”
What it means: This enables the FIA to set the recharge limit even lower than 7MJ at 12 races, providing the governing body with an additional tool to address excessive superclipping in qualifying. Twelve races represent half the calendar, allowing the FIA to customize the recharge limit for all circuits where energy management is most critical. Ideally, to replicate the previous style of qualifying, all harvesting would occur under braking or in grip-limited sections of the circuit, but it is likely that some will still need to be executed in high-speed corners or at the end of straights via superclipping.
Race
The FIA’s explanation: “The maximum power available through the Boost in race conditions is now limited to +150 kW (or the car’s current power level at activation if higher), restricting sudden performance disparities.”
What it means: Previously, the ‘Boost’ allowed drivers to access the full 350kW of the MGU-K with the push of a button. In extreme cases, this could mean transitioning from minimal electric power to full electric power, but now the additional boost (on top of the power already supplied by the MGU-K) is capped at 150kW. This still represents a 200bhp boost, which is considerable, but should help limit dramatic speed differences like the one that led to Oliver Bearman’s accident in Japan.
The FIA’s explanation: “MGU-K deployment is maintained at 350 kW in key acceleration zones (from corner exit to braking point, including overtaking zones) but will be restricted to 250kW in other areas of the lap.”
What it means: By reducing the deployment of electrical energy by 100kW in sections of the circuit where overtaking is less likely, particularly flat-out corners, there will be fewer instances of significant speed disparities in hazardous areas of the track. By retaining 350kW deployment in areas where overtaking is most probable β along the straights β the fluid racing observed thus far this year should continue.

Race starts
The FIA’s explanation: “A new ‘low power start detection’ system has been developed, capable of identifying cars with unusually low acceleration shortly after clutch release. In such instances, automatic MGU-K deployment will be activated to ensure a minimum level of acceleration and mitigate start-related risks without providing any sporting advantage. An associated visual warning system is being introduced, activating flashing lights (rear and lateral) on affected cars to alert following drivers.”
What it means: According to the regulations, the MGU-K is prohibited from deploying any electrical power at the start until the car reaches 50km/h. This rule exists to prevent teams from engineering a form of launch control into the start process, but it will now be overridden if the car’s petrol-powered start is so poor that electrical energy is needed to assist in the getaway. This should help minimize the number of alarming situations where a car fails to move and becomes a stationary obstacle for the cars behind it on the grid. Lights will flash at the rear of the car to warn those behind that the system has been activated.
The FIA’s explanation: “A reset of the energy counter at the start of the formation lap has also been implemented to rectify a previously identified system inconsistency.”
What it means: An inconsistency in the original regulations meant that a driver’s starting position on the grid (either before or after the timing line) influenced how much energy could be harvested during the formation lap. When drivers left the grid for the formation lap, those who started beyond the timing line were counted within that lap, and thus already within the recharge limit for that lap when they utilized a significant amount of energy for their practice start. Those behind the timing line could perform a practice start and then were allowed a full recharge limit for the formation lap. At the opening round in Australia, this meant some drivers depleted nearly all their battery while warming their tires with burnouts to the grid and were left with minimal battery for the actual start. Teams adapted their processes for China and Japan, but this change will standardize the situation for everyone.
Wet conditions
The FIA’s explanation: “Tyre blanket temperatures for intermediate tyres have been raised following driver feedback to enhance initial grip and tyre performance in wet conditions.”
What it means: This adjustment is unrelated to the energy recovery system and focuses on ensuring the tyres are at the appropriate temperature when fitted to the car to provide optimal grip.
The FIA’s explanation: “Maximum ERS deployment will be reduced, limiting torque and enhancing car control in low-grip conditions.”
What it means: This will result in a decrease in the electrical power available in wet conditions, which had the potential to make the cars challenging to control. Unlike the power curve of a traditional engine, which builds gradually, electric power is delivered almost instantaneously and could catch drivers off guard in difficult conditions.
The FIA’s explanation: “The rear light systems have been simplified, providing clearer and more consistent visual signals to improve visibility and reaction time for following drivers in adverse conditions.”
What it means: The rear lights serve not only in wet conditions but also as a means to communicate the deployment status of energy for the car in front. This system should ensure that drivers are not taken by surprise if the car ahead ceases to deploy electrical energy and slows down.
Will these changes make a difference?
The effectiveness of these changes will only become clear after several races across different circuit types. The fundamental challenge of generating nearly half the car’s power output from a relatively small battery persists, and the necessity to manage energy throughout the lap will remain evident when the battery is depleted and superclipping is implemented.
Qualifying laps will be slower due to the reduction in the amount of power that can be recovered (and thus utilized) during the lap, but this loss in lap time will primarily be felt during acceleration onto long straights.
By limiting the energy that can be harvested per qualifying lap by 12.5%, it should help address some of the concerns raised by drivers during the first three races, but the FIA will likely need to fully utilize its capacity to further lower the recharge limit at some of the more energy-restricted circuits to achieve the desired effect.
In the races, the new 150kW cap on the Boost should help mitigate the kind of closing speeds that contributed to Bearman’s accident (where he was on full boost while Franco Colapinto’s Alpine was operating without any battery support), while restricting the use of 350kW power to designated overtaking areas should ensure that drivers are not confronted with significant closing speeds in hazardous sections of the circuit. F1 has been eager to maintain the fluid overtaking seen in the first three races β often referred to as yo-yo racing β and, for better or worse, that should continue even with the changes.
However, assessing numbers on a page without the benefit of the simulations that teams and the FIA have been able to analyze β or the real-world testing that will only be feasible from Miami onward β means it is premature to make a conclusive assessment. F1 and the FIA have left the possibility open for additional adjustments this year before the chance to implement more significant changes, if necessary, will be reserved for 2027.
